摘要：

The 9-O-beta-D-glucopyranoside of 3-hydroxy-7,8-didehydro-beta-ionol (1) has been isolated from a glycosidic XAD-2 extract obtained from rose petals. In addition to the beta-damascenone-generating compound 1, the following glycoconjugates have been isolated and characterized as peracetates: 3-hydroxy-7,8-dihydro-beta-ionol 9-O-beta-D-glucopyranoside (2), 3-hydroxy-7,8-dihydro-beta-ionol 3-O-beta-D-glucopyranoside (3), 2-phenylethyl-O-beta-D-glucopyranoside (4), 2-phenylethyl-O-beta-D-galactopyranoside (5), benzyl-O-beta-D-glucopyranoside (6), (2E)-2,6-dimethyl-6-hydroxyocta-2,7-dienyl-O-beta-D-glucopyranoside (7), (2Z)-2,6-dimethyl-6-hydroxyocta-2, 7-dienyl-O-beta-D-glucopyranoside (8), and (2E,6E)-2,6-dimethyl-1-hydroxyocta-2,6-dien-8-yl-O-beta-D-glucopyranoside (9).
